Packaging and releasing to Pypi

[pschmitt]

To make things cleaner it'd be great to write a setup.py file and release it to Pypi.

I've started working on this on my fork, see https://github.com/pschmitt/Roomba980-Python/tree/packaging

I'm not submitting a PR for this change now since it is incomplete for now and needs to be rebased.

• [x] Packaging
• [ ] Release to pypi

Now that #6 has been merged, would you mind uploading the current version to Pypi?

I went ahead and uploaded it as roombapy.
